Description
Technical field
Technical field of transmission equipment is the utility model is related to, is specifically a kind of crank forged piece.
Background technology
Crank is the important part in a kind of common transmission machinery, wherein crank usually with connecting rod cooperating,
It is that such as engine realizes working cycles, completes the main movement part of energy conversion.Crank is generally divided into straight type crank and cone
Shape crank, the pedestal of straight type crank is straight cylindrical arrangement, and the pedestal of taper crank is taper configurations, and straight type crank or cone
The concrete structure of shape crank should be engaged with engine structure and link mechanism.Crank forged piece is the predecessor of crank, and crank is logical
Cross what is be processed further on crank forged piece, therefore the performance of crank is influenced between the structure of crank forged piece and uses effect
Fruit, crank forged piece still needs to multiple reprocessing steps after forging molding could form available finished product, but existing crank
Forging is relatively simple in structure, and reprocessing positioning step is more, causes the influence that manufacturing cost is high.
Utility model content
The technical problems to be solved in the utility model is in view of the above shortcomings of the prior art, there is provided a kind of rational in infrastructure easy
The crank forged piece of reprocessing.
To achieve the above object, the utility model provides following technical solution：A kind of crank forged piece, including crank axle is with matching somebody with somebody
Weight portion, the generally tapered round platform axis of the crank axle, crank axle bottom are equipped with the axis platform being connected with counterweight part, the counterweight
Portion includes counterweight pan portion, central axle portion and lower interlocking bar portion, and the counterweight pan portion is in fan-shaped disk body, and lower interlocking bar portion is in round inclined
Platform, the central axle portion connection counterweight pan portion and lower interlocking bar portion, axis platform and the center axis center of the crank axle are connected,
The counterweight pan portion is equipped with profile protrusion arc side with lower interlocking bar portion upper surface outer end edge.
As further program of the utility model：The thickness of the upper counterweight part is more than lower interlocking bar mounting portion.
As further program of the utility model：The lower interlocking bar mounting portion lower face is equipped with circular protrusions.
As further program of the utility model：The crank axle taper is 1:10-1:20.
Compared with prior art, the beneficial effects of the utility model are：The utility model product is by the way that existing crank is forged
Part is arranged for ease of the structure of reprocessing, and is provided with profile protrusion arc side in counterweight pan portion and lower interlocking bar portion, overall along song
Arbor is symmetrical, and integral surface simple smooth, and the low yields of solid forging cost is high.
Brief description of the drawings
Fig. 1 is the side structure schematic diagram of the utility model embodiment.
Fig. 2 is the positive structure diagram of the utility model embodiment.
Fig. 3 is the backsight structural representation of the utility model embodiment.
Reference numeral therein is：Crank axle 1, axis platform 2, counterweight pan portion 3, lower interlocking bar portion 4, central axle portion 5, upper profile

All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-3, in a kind of embodiment of the utility model, a kind of crank forged piece, including crank axle 1 and counterweight
Portion, the generally tapered round platform axis of the crank axle 1, crank axle bottom are equipped with the axis platform 2 being connected with counterweight part, the counterweight
Portion includes counterweight pan portion 3, central axle portion 5 and lower interlocking bar portion 4, and the counterweight pan portion 3 is in fan-shaped disk body, and lower interlocking bar portion 4 is in
Round inclined platform, the central axle portion 5 connect counterweight pan portion 3 and lower interlocking bar portion 4, the axis platform 2 of the crank axle with central shaft
The heart is connected, the counterweight pan portion 3 and lower 4 upper surface outer end of interlocking bar portion along profile protrusion arc side is equipped with, be respectively on
Profile protrusion arc may be such that crank end face is wear-resistant, the thickness of the upper counterweight part is more than in 301, bottom profiled protrusion arc 401
Lower interlocking bar mounting portion, the lower interlocking bar mounting portion lower face are equipped with circular protrusions, and the crank axle taper is 1:10-1:
20, crank axle taper is 1 in the present embodiment:15 as preferred.
The principle of the utility model is：The utility model product by existing crank forged piece by being arranged for ease of reprocessing
Structure, and profile protrusion arc side is provided with counterweight pan portion 3 and lower interlocking bar portion 4, it is overall symmetrical along crank axle 1, and
And integral surface simple smooth, the low yields of solid forging cost are high.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
